Currently, USB is forced-enabled for the sunxi familly, and there is no way to disable it.
However, USB takes a long time to initiliase, delaying the boot by up to 5 seconds (without any USB device attached!). This is a very long delay, especially in cases where USB booting is not wanted at all, and where the device is expected to boot relatively often (even in production).
Change the way the dependencies are handled, by only forcibly selecting USB when CONFIG_DISTRO_DEFAULTS ("defaults suitable for booting general purpose Linux distributions") is set. This option defaults to y for the sunxi familly, so the current default behaviour is kept unchanged. Users interested in boot time and/or size will be able to disable this to further disable USB.
With USB disabled, the time spent in U-Boot before handing control to the Linux kernel is about 1s now, down from ~5s (Nanopi Neo, sunxi H3).
Just a gentle ping... ;-)
10 days is a bit short in between ping times for a volunteer maintained subsys :)
Sorry, I'm just new on the U-Boot list, so I'm not sure what the usual round-trip is. ;-)
Anyways I've this on my todo and hopefully will get around to it soonish.
Thanks! You'll get a beer next time we meet for ELC-E.
(What? Bribery does not help? Ohh.. ;-) )
